What is the difference between three address instruction and two address instruction?
the differebce between three address instruction and two address instruction is three adresss instructoion two address instruction 1) here 3 oprarend fields are used 1) here 2 oprerand fields are used 2) the result is stored in 3rd operand 2) here the result is stored in 2nd oparend
What is 3 byte instruction in microprocessor?
A two-byte instruction gives the specific function instruction in two bytes, or two words. The first specifies the opcode, which tells the microprocessor what operation will occur. The second specifies the operand, or the data that the operation is done on.
What is instruction format in computer architecture?
The connection between the hardware and software components of a computer creates the computer architecture. It is basically how the components are connected to form a complete system. Sir Frederick P. Brooks and Sir Lyle R. Johnson presented the idea of computer architecture in 1959. A set of operating codes, operands, an opcode, and an addressing mode make an instruction. The instruction format is the standard instruction format that is directly used by the CPU. The instruction format is just the sequence of bits (0,1). The group of these bits is called a field. Each field of the system provides specific information for a particular task to the CPU about the instruction's operation and the instruction's data. The most fundamental difficulty in format design is instruction length. The longer the command will, take longer the time to fetch it. The types of Fields are discussed below: Operation Field: It specifies the operations that are performed by the instructions like, ADD, SUB, etc. It can be any value or number on which the task has been performed. Operation field is mandatory for every instructor Address Field: It specifies the address of the operand. It refers to the address where the operand is stored. On the basis of multiple address fields, the instruction is categorised as follows: Zero address instruction: The operand positions are implicitly represented in zero address instructions. The stack-organized computer system supports these commands. One address instruction: This instruction manipulates data with the help of an implicit accumulator. Accumulator is a register that performs a logical process for the CPU. It uses one address field. Two address instructions: This address instruction is mostly used. This address command format has three operand fields. In the two address sections, registers or memory addresses can be used. Three address instructions: A three-address command must contain three operand components in its format. These three fields could be registers or memory locations. The instruction pipeline in computer architecture The instruction pipeline in computer architecture shows the system's instruction flow. It has 4 major segments, which are discussed below. Segment 1: The instruction fetch part can be performed using first in, first out (FIFO) buffers. Segment 2: The second section decodes the memory-fetched command before the effective location is computed in a different arithmetic circuit. Segment 3: The input is fetched from memory. Segment 4: The execution of the instructions is performed. Some of the features of instruction are : Addressing model: This is the first part of the instruction format. Data over the instruction format can be represented as an addressing format, and data is stored in the computer's memory or in the CPU's register OPCODE(operation code): This is the second part of the instruction format, and the opcode instructs the processor to perform the desired operation. Operand: Depending upon the processor instruction format, it contains zero to three operands, and this part specifies the data or points to the address of the data.
How many syllables are in the word instruction?
Three
What is computer instruction?
A computer instruction is a command given to the computer to perform an operation.There are three instruction code formates.Memory - reference instructionRegister - reference instructionInput - output instructionIf you mean "Computer Instruction" as a field of study, then that is learning how to use computers.
How many fetch cycles a three byte instruction requires for its execution?
There are three fetch cycles in a three byte instruction. The first one is four clock cycles long, while the other two are three clock cycles long. Depending on what the instruction does, there will then be more read/write cycles.
What is the definition of instruct?
Instruction has three meanings: 1. An instruction is something that someone tells you to do. 2. If someone gives you instruction in a subject or skill, they teach it to you. 3. Instructions are clear and detailed information on how to do something.

Explain steps involve in instruction execution cycle?
The two-phase process for executing instructions on a typical CPU involves a fetch step and an execute step. Fetch is where the instruction is loaded from memory and execute is where the actions detailed in the instruction are carried out.
What are suffixes for instruct?
The verb instruct has the abstract noun form instruction.
What will be the content of program counter of 8085 mpu has fetched machine code located at the memory location 205FH?
It depends on whether the machine code is one, two, or three bytes long, and on whether or not the instruction transferred control to another location. In the case of a non-jump single byte instruction, the PC will have a value of 2060H after the instruction is complete, and it will be 2061H or 2062H after a two or three byte instruction. In the case of a jump, call, or interrupt, the PC will depend on the instruction.
What no of instruction will be execute by using only one clock pulse in 8085 microprocessor?
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
